Leakage Test
Warning
Mains voltage applied to appliance
The Leakage Test shows the current being lost through Leakage as
the difference in the currents flowing in the Live and the Neutral
conductors. This difference is the total leakage away from the
appliance, and is generally equivalent to the current flow through the
earth lead of the appliance, and displays the result in milliamps (mA).
This differential method of determining leakage will show the full
leakage of an appliance in-situ, so if the appliance has an extra earth
point, i.e. water pipe, then the Tester will show the full and true
appliance leakage. This is also known as Enclosure or Differential
Leakage.
Touch Leakage Test
Warning
Mains voltage applied to appliance
The Touch Test displays the current that would flow if the appliance
was touched by a person. This is based on a ‘body model’ of 2k
Ω.
The Tester detects any current flowing in the Earth Bond Lead
(attached to an appropriate point on the appliance) and indicates the
potential leakage through a metal panel. The Tester displays the
result in milliamps (mA).
